A Queensland-based energy supplier has been fined $300,000 in a decision handed down in the Rockhampton Magistrates Court.
The energy supplier pleaded guilty to a Category 2 offence for failing to ensure an overhead powerline and its supporting structures spanning farmland were safe. A power pole in the field was kept vertical by a number of stay wires, each of which were separately attached to the ground. There were guards at the bottom of each stay wire obscuring a portion of it.
The power pole was inspected in late September 2020, during which corrosion was noted and given a Priority 3 rating, meaning it did not require rectification within a particular time frame. Ten months later, employees were working underneath the overhead powerline with a harvester when the top of it either contacted or came very close to the powerline.
One worker was electrocuted and died, and another five received electric shocks and were hospitalised.
The charge arose out of a failure by the defendant to have a system of routine visual inspection of the entire length of the stay wires, including the portions covered by the guards. One of two stay wires became corroded and broke, allowing the power pole to shift and the powerline to drop. When the pole was straightened after the incident, the powerline height over the machinery rose more than three metres. The energy supplier subsequently amended its inspection process to require routine inspection of stay wires underneath the stay guard.
